Air Pollution and Photosynthesis
Air pollution can affect photosynthesis adversely. For example, smog can block out light that is needed for photosynthesis, affecting photosynthesis through which plants convert CO2 to sugars and oxygen.
Air pollution can also cause “acid rain.” Acid rain is a popular term for the atmospheric deposition of acidified rain, snow, sleet, hail, acidifying gases and particles, as well as acidified fog. Acid rain harms the leaves of a plant, which reduces how well it can conduct photosynthesis.
